Keystone KT-LED10PSWD-4A9CSFDIM-B Led Downlight 10W 4in

Product Description

The KEYSTONE KT-LED10PSWD-4A9CSFDIM-B is a 4-inch LED slim wafer downlight retrofit designed to replace standard recessed fixtures using an E26 lamp base. It offers field-selectable wattage at 10W, 8W, or 6W, and field-selectable color temperature across five settings: 2700K, 3000K, 3500K, 4000K, and 5000K. The black trim integrates flush against the ceiling for a clean finish. Triac dimming support makes this fixture compatible with standard wall dimmers already installed in most residential and light commercial spaces. Electricians and lighting contractors install this unit as a direct retrofit without cutting new holes or running additional wiring.

This downlight retrofit is suited for residential and light commercial applications where recessed lighting is already in place. The slim wafer profile fits into shallow ceiling cavities where conventional housings will not fit. The selectable wattage and CCT settings allow a single SKU to serve multiple jobsite specifications, reducing stocking complexity. Quick disconnect wiring simplifies the swap from an existing E26 socket to the new LED wafer module. Typical install locations include living rooms, hallways, kitchens, offices, and retail spaces requiring flexible, dimmable downlighting.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. Turn off the circuit breaker controlling the fixture before removing the existing lamp and connecting the wafer module. Confirm that the wall dimmer on the circuit is rated for LED triac dimming loads to avoid flickering or buzzing. Verify the ceiling cavity depth is sufficient for the slim wafer housing before beginning work.
